Steel-Insert Locknuts for Extreme Vibration—Grade 5

When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration. These locknuts are often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 5 steel,they're suitable for fastening most machinery and equipment.

Metric Steel-Insert Locknuts forExtreme Vibration—Class 8

The steel insert grips the threads and lifts away from the nut body when installed, isolating the insert from the nut’s load to resist spinoff caused by vibration. These locknuts are often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Comparable in strength to Class 8.8 bolts,they're suitable for fastening most machinery and equipment.

These locknuts are about 10% wider and taller than standard steel-insert locknuts. They distribute the load over a large area. When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration.They're often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 8 steel,they're about 25% stronger than medium-strength steel locknuts.

These locknuts are about 10% wider and taller than standard steel-insert locknuts. They distribute the load over a large area.

The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 5 steel,they're suitable for fastening most machinery and equipment.

Thin Steel-Insert Locknuts for Extreme Vibration

About two-thirds the height of standard steel-insert locknuts, use these in low-clearance applications or jam one against a hex nut to hold it in place. When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration.They're often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 5 steel, these nuts are suitable for fastening most machinery and equipment.
